Nyronia

Written in ruby, Nyronia is an engine designed to allow non-programmers to write adventures for text-based games. The program reads adventures from formatted text files and generates a playable world with items, actors and events. It comes with a basic adventure prewritten to show what the engine is capable of, and allow users to see how to write adventures of their own.
